Kanban (Japanese: 看板 meaning signboard) is a scheduling system for lean manufacturing (also called just-in-time manufacturing, abbreviated JIT). [2] Taiichi Ohno, an industrial engineer at Toyota, developed kanban to improve manufacturing efficiency. [3] The system takes its name from the cards that track production within a factory.
The diagram here shows a software development workflow on a kanban board. [4]Kanban boards, designed for the context in which they are used, vary considerably and may show work item types ("features" and "user stories" here), columns delineating workflow activities, explicit policies, and swimlanes (rows crossing several columns, used for grouping user stories by feature here).
Kanban can be used to organize many areas of an organization and can be designed accordingly. The simplest kanban board consists of three columns: "to-do", "doing" and "done", [3] though some additional detail such as WiP limits is needed to fully support the Kanban Method. [4] Business functions that use kanban boards include:
3. Kanban: Increased Visibility of WIP and Limiting Multitasking. Kanban is a project management methodology focused on increasing efficiency and releasing early and often with a collaborative and ...
It is effectively an amalgam of MRP for planning, and kanban techniques for execution (across multi-echelon supply chains) which means that it has the strengths of both but also the weaknesses of both, so it remains a niche solution. The problems with MRP (as listed above) also apply to DDMRP. Additional references are included below. [11] [12 ...
Visual control is a business management technique employed in many places where information is communicated by using visual signals instead of texts or other written instructions. The design is deliberate in allowing quick recognition of the information being communicated, in order to increase efficiency and clarity.
Production Kanban is designed for a replenishment quantity that may be smaller than a lot size or batch. It is based on a "dual card Kanban" system where a "move" card or container represents the quantity required by the downstream point of consumption and a "produce" card is kept on a display board and accumulates to a replenishment batch.
Lean IT is the extension of lean manufacturing and lean services principles to the development and management of information technology (IT) products and services. Its central concern, applied in the context of IT, is the elimination of waste, where waste is work that adds no value to a product or service.
